I think maybe 340 to 360 is fair.
I'd just drop but 100 even to 380 and fix the reinforce bug. Plus, if USf weapon teams had something done about the squad size and or received accuracy that would be enough to fix the unit. It is rather a strong unit and seriously hurt blobs. Also it gets those pretty gnarly shells at vet 2.
As to all the talk about recon doc. I don't get it - it's one of the more unique and interesting docs in the game and especially the USF, but functionally it just falls flat. Rifleman observers needs to be fixed and buffed, M8 needs some kind of buff - honestly, the way I see it just make it a more anti-infantry version of the Stuart with cost to balance(just make canister shot pin infantry but do little damage...), Last air dropped combat group REALLY needs to be looked into. I like my suggestion best of course, but I've heard plenty of ideas about it that would be 100% better than the nonsense it is now - Light AT mines? On paratroopers? At CP 7? Really?? Relic???? WHY ARE MY ELITE LATE GAME PARATROOPERS DROPPING WITH RANDOM WEAPONS, EQUIPPED ONLY WITH AT MINES, AND HAVE AN UNMANNED AT GUN DROPPED WITH THEM. HOW DID THIS MAKE IT OUT OF THE ALPHA, MUCH LESS INTO THE GAME AT ALL.
If we wanted to make air dropped even simpler just have a regular paratrooper at CP3, or implement rangers at CP2... just some thoughts.
